50 Cent sued for copyright infringement

New York: Rap superstar 50 Cent has been sued for copy right infringement by a little-known rapper called Caliber.

The Atlanta rapper has sued 50 Cent for an unspecified amount, claiming that he has the exclusive rights to a instrumental track used by 50 Cent in his 2007 hit `I Get Money`, reported New York Post online.

Caliber has filed a lawsuit in New York Federal Court against the rapper, along with the producer of the hit song, `I Get Money` and a host of music industry companies.

The 28-year-old states that he bought the exclusive license from producer William `Apex` Stanberry, giving him sole ownership over the track and 50 Cent knowingly took the instrumental and used it in the song which appeared on his third album `The Massacre`.

`I Get Money` was released in June 2007, peaking at number 4 on Billboard Hot Rap Tracks chart. The single, which was named as one of the best tracks of the year by Rolling Stone and Time, later spawned a high voltage remix featuring Diddy and Jay-Z.
